Definitions
- the invention relates to a transmission for positive torque transmission between two shafts according to the preamble of claim 1, a working machine, in particular a mixer with the mentioned transmission according to claim 14, a drive unit with the mentioned transmission according to claim 15 and a unit for converting the energy of a flowing medium in a torque with the mentioned gear according to claims 16 and 17.
- the device based on the principle of the reversible cube chain corresponds much better to the movement character of the flowing media, air and water, and therefore works with a significantly higher degree of efficiency. Thanks to the special movement characteristics inherent in the cube chain, the rolling and rolling movements of air and water capture the vane-like and wing-like driver elements of this device as if they were part of the medium flowing around them. By specifically directing the medium, flows can be achieved which further increase this tendency.
- the connection of such driving elements with parallel axes working on the principle of the reversible cube chain leads to a non-uniform rotational movement of these axes, which can be corrected if necessary by a mechanism with universal joints and conical gear wheels.
- the invention seeks to remedy this.
- the invention has for its object to relieve the joints between the links belonging to the cube chain by a positive torque transmission between the two shafts, which are attached to the ends of a chain based on the principle of the reversible cube with moving links, so that the frictional forces reduce and thus improve the efficiency of the device. This is irrespective of whether the device is used as a drive or for converting the energy of a flowing medium into a torque.
- the principle of the invertible cube is based on a spatial movement system, which consists of individual rigid connecting links, which are connected to one another by swivel joints, which have only one swivel axis and are successively rotated by 90 ° to one another, to form a movable, ring-shaped association and this association can be inverted . If, for example, the device is operated as a wind wheel and the torque derived from the wind energy is taken off on one of the rotating shafts, or also on both, an uneven rotational movement necessarily results due to the kinematics inherent in the cube belt.
- the difficulty of such devices is that the two shafts to be driven have to rotate non-uniformly if a uniform distribution of the two alternately required accelerations or decelerations in the movement sequence of the device is to be achieved. If this condition is not met, the device to be moved moves irregularly.
- the invention solves the problem with a gear with oval gears, which has the features of claim 1, a working machine, in particular a mixer with the mentioned gear according to claim 14, a drive unit with the mentioned gear according to claim 15 and a unit for converting the Energy of a flowing medium into a torque with the mentioned transmission according to claims 16 and 17.
